LibriVox recording of Opticks, by Isaac Newton.
Read by Librivox volunteers.
The famous physicist Sir Isaac Newton lectured on optics from 1670 - 1672. He worked on the refraction of light into colored beams using prisms and discovered chromatic aberration. He also postulated the corpuscular form of light and an ether to transmit forces between the corpuscles. His "Opticks", first published 1704 contains his postulates about the topic. This is the fourth edition in English, from 1730, which Newton corrected from the third edition before his death. (Summary by Ava)
